Our verdict
Budget-conscious Android or iPhone users who want an AMOLED display, built-in dual-band GPS, calls, and multi-day battery life.
The CMF Watch 3 Pro is an affordable round smartwatch with a 1.43-inch 466 x 466 AMOLED display, 60Hz refresh rate, and brightness rated up to 670 nits. It adds dual-band L1/L5 GPS, Bluetooth calling, heart-rate, blood-oxygen, sleep, and stress tracking, plus IP68 dust and water resistance. CMF rates the 350mAh battery for up to 13 days of typical use, 10 days of heavy use, or roughly 4-4.5 days with the always-on display. Independent reviews reported about six to seven days with heavier real-world settings and praised the improved GPS. It offers strong everyday value, but it is not a medical device, uses a proprietary magnetic charger, and IP68 does not make it a dedicated swimming watch.
What we like
- The 1.43-inch 466 x 466 AMOLED display supports 60Hz refresh and an always-on mode.
- Dual-band L1/L5 GPS is a meaningful upgrade for outdoor route tracking at this price.
- Bluetooth calling and phone compatibility work through the Nothing X app on Android and iOS.
- The 350mAh battery is rated for up to 13 days under CMF's typical-use conditions.
- Heart rate, SpO2, sleep, stress, workouts, notifications, and gesture controls cover the main everyday smartwatch functions.
Keep in mind
- Independent reviews achieved closer to six or seven days with heavier settings, below the 13-day best-case claim.
- Always-on display reduces the manufacturer estimate to roughly four to 4.5 days.
- The proprietary magnetic charging puck can be displaced more easily than a standard USB-C connection.
- Health readings are wellness estimates rather than medical measurements, and IP68 should not be treated as proof of suitability for swimming.
Who should buy
Budget-conscious Android or iPhone users who want an AMOLED display, built-in dual-band GPS, calls, and multi-day battery life.
Who should skip
Users who need medical-grade health data, a full app ecosystem, cellular service, contactless payments, or a dedicated swim-training watch.

FAQ
How long does the CMF Watch 3 Pro battery last?
CMF claims up to 13 days for typical use, 10 days for heavy use, and around four to 4.5 days with always-on display. Independent reviews commonly reported about six to seven days with heavier settings.
Does the CMF Watch 3 Pro have built-in GPS?
Yes. It supports dual-band L1/L5 positioning plus major satellite systems for phone-free route recording.
Can it make Bluetooth calls?
Yes. The watch includes a microphone and speaker for Bluetooth calls when connected to a compatible Android phone or iPhone.
Can you swim with the CMF Watch 3 Pro?
It carries an IP68 rating, but that is not the same as a swim-depth rating. Independent reviews also note limitations around swim tracking, so it is not the best choice for dedicated pool workouts.
